Choose the correct alternative answer for the following questions.
sinθ cosecθ = ?
A. 1
B. 0
C. 𝟏𝟐
D. √𝟐
Solution
The correct answer is A. 1.
We know that:
sinθ = 1/cosecθ
Multiplying both sides by cosecθ, we get:
sinθ cosecθ = 1
Therefore, sinθ cosecθ = 1.
Explanation:_
We know that:
cosecθ = 1/sinθ
Therefore,
sinθ cosecθ = sinθ × 1/sinθ = 1
Hence, the correct answer is option A: 1.
